IMPROVEMENT IN HARVESTERS.

Specification forming partof Letters PatentNo. 83,627, dated November 3,1868.

To all whom 'it may concern:

Be it known that I, MARTIN HALLENBECK, of the city and county of Albany,in'the State of New York, have invented. certain new and usefulImprovements in Harvesters, of which the following is a full, clear,and. exact description, reference being had to the accompanyingdrawings, which make part of this specification, and in which- Figure lrepresents a plan, and Fig. 2 an elevation, of my improved harvester.Fig. 3 represents a plan view of a portion of the heel end of thecutting apparatus.

My invention relates to that class of harvesters known as two-wheeledfront-cut machines. Its object is to enable the cutting apparatus toconform freely to the undulations of the ground without the use of ajoint in the finger-beam or shoe; and the improvement herein claimedconsists, first, in a novel method of combining a main frame,oscillating with an axle supported on two wheels, with a footboardcarrying the tongue, the lifting lever, and the drivers seat, andpivoted to the frame behind the main axle, so that the Weight of thedriver constantly tends to elevate the cutf ters and cause them to runlightly over the ground; second. in a novel method of securing theEnger-beam to a shoe carrying a socket arranged transversely to thefinger-beam, and rocking axially in bearings or down hangers beneath amain frame oscillating vertically on its axle, whereby the cuttingapparatus is free to conform to the undulations of the ground withoutthe use of a joint in the Enger-beam; third, in a novel method ofpreventing the pitman from escaping from the sickle eye by means of anadjustable ilanged slotted guardplate on the finger-beam.

In the accompanying drawings, two driving and supporting wheels, A A',are shown as mounted on an axle, B, fixed on the main frame C, which is,by preference, made of metal. The tongue D is bolted to a socket, cl, onthe foot-board E, which has two lugs, e, pivoted to the frame behind theaxle, so as to allow free vertical play to both the tongue and frame. Bythis arrangement the pull on the tongue and the weight of the driveracton the main frame in rear of the axle, and thus tend tocounterbalance the pressure of the cutting ap paratus on the ground, andmake the machine run lightly. This arrangement likewise enables me tolift the cutting apparatus easily by the lifting -lever when movingforward, and in backing the tendency is also to lift the cutters. Thedrivers seat F is mounted on a standard, f, secured to the foot-board.Alifting-lever, G, of well known construction, is pivoted to the grainside of the foot-board.

Two down-hangers or stirrups, h h1, support in proper sockets a pin, h2,on which a tubu lar socket, I, fits, and is held by a set-screw, t'.This socket is rigidly secured to or cast in one piece with the shoe J,which is provided with a leading-Wheel, K, of the usual form. A lever,H, has an eye on its lower end, through which the pin h2 passes andbears against one edge of a slot in the socket. The upper end ofthislever bears against the under side of the foot-board, and thus liftsthe divider end of the cutting apparatus by rocking the socket axiallyon its pivot as the main frame is raised. The finger-beam L is providedwith guardfingers and cutters of the usual construction, and is securedto the shoe by bolts l, passing through the shoe, the Enger-beam, andthrough a block, m, which serves to guide the cutters and keep them intheir properv position. By this mode of construction these parts caneasily be removed and replaced.

In order to prevent the pitman -head from flying out of its socket inthe cutterbar, a iianged plate, N, is provided Withpa diagonal slot, a,through which a set-screw passes into the iingerbeam. The flange canthus be set nearer to or farther from the sickle eye, and, when securedin place, holds the pitman-head in the eye of the sickle without otherfast enmg.

Internally-geared spur-wheels O on the drivingwheels drive correspondingpinions o, provided with suitable backing-ratchets, and mounted on acounter-shaft, P, behind the main axle, and carrying a bevel-wheel, It,which drives a corresponding pinion, s, on a crank-shaft, S, turning inabox on the main axle, and in another box on the front cross-bar of themain frame. A balance-wheel, T, on the crankshaft carries a wrist-pin,t, which drives the cutters by a pitman, u, in the usual way.

The operation of the machine is obvious.

described, vof the main frame, the down-han g- The tongue is supportedby the team. The main frame oscillates freely with the main aXle. Thefinger-beam rises and falls with the main frame, and also oseillates outhe pin h2. When the nger-beam is raised by the driver the 1ever Hstrikes the foot board and lifts the divider end of the cuttingapparatus by turning the sleeve I on its pivot h2.

What I claim as my invention, and desireto secure by Letters Patent, is-

l. The arrangement, as described, for joint operation, of the tongue,the drivers seat, and Y 2. The arrangement, for joint operation, as

ers h h1, the lever H, the socket I, and the cutting apparatus.

3. The combination, as described, with the sickle-eye and pitman, oflthe an ged slotted guard-plate N, for the purpose specified.

In testimonywhereof IV have hereunto subscribed my name.
